I bought a green cheek conure about a month ago. He was abused in the pet shop and the owner told me he needs training. Everything was going really well for a while; we got him to eat out of our hands and come about 10 inches from us. Then we got him a bigger cage and he seemed to take to it really well. I noticed he was eating my bamboo plant so i took it away. Then out of nowhere he started attacking my husband; flying at his face, puffing up and doing a spitting noise. He is also stalking my baby! Any ideas on what i should do to stop this behavor?
